Unfortunately this isn't going to work, and there's no point in applying again and again. You should've applied for Spousal Sponsorship + Visitor Visa (expressing dual intent) from the beginning. They will always see you (and then your unborn child) as a "strong tie" and assume he will not go back once his authorized stay is complete. Nothing else, nothing, will trump or supercede the strength of tie of spouse and child, regardless of his job, status, properties, and business in India.
Best would've been to (and I'm not judging), but for anyone else in similar boat and is reading this post, please do family planning accordingly because this is a very crucial time for all mothers to be, and they need all the emotional, mental, physical support they require. The anxiety and panic attacks, mood swings, and the need of having the spouse nearby is of utmost importance.
